I've also encountered this bug in current release of CentOS 7.4.1708 (3.10.0-693.11.1.el7.x86_64). I'm running uptimed on a few units as well (Ubuntu 17.10 4.13.0-16-generic & MacOSX 10.11.6 [15G17023] 15.6.0) - and I havn't had any problems with negative uptime reports from those. This problem/bug must be something that isn't always showing, since it hasnt been fixed yet. I believe there's something 'else' that is interacting when it shouldn't - that isn't something default in the system. I hope we, or someone, can get to the bottom of this problem.
